ALBERT STOCKWELL, OF PROVIDENCE, RHODE ISLAND.

DEVICE FOR OPERATING WATER-CLOSET OR OTHER VALVES.

SPECIFICATION forming part of Letters Patent No. 414,340, dated November5, 1889.

Application filed May 27, 1889. Serial No. 312,209- (No model.)

To all whom it may concern.

Be it known that I, ALBERT STooKwELL, of Providence, in the State ofRhode Island, have invented a new and useful Device for Operatingater-Closet and other Valves; and I do hereby declare that the followingspecification, taken in connection with the drawings making apart of thesame, is a full, clear, and exact description thereof.

Figure 1 is a front view of my device, with elevation of tank and valve,showing latter closed. Fig. 2 is a side view of same. Fig. 3 is anotherfront view showing valve open. Fig. A is a side view of same. Fig. 5 isaview of the valve.

The object of my invention is to produce a device for operating valveswhere water is used for flushing purposes which shall be more prompt,accurate, and satisfactory in its operation than those in use; and itconsists in the construction, arrangement, and combination of theseveral parts and features, as hereinafter described.

My invention is more particularly designed for use in connection withwater-closets, although it may be adapted to other uses where it isdesirable to regulate the discharge of water from a flushing-tank.

In the drawings, A is the tank, containing water or other flushingliquid.

B is a valve within the tank A, communicating with a conducting-pipe.

Extending across the top of the tank A, and held in suitable bearings,is a rotating shaft C. lVithout the tank and fixed upon one end of theshaft 0, somewhat eccentrically thereto, is a hollow cylindrical pulleyD, partially filled with liquid. Upon the shaft 0 and directly over thevalve is a fixed pulley E, to which is attached and upon which is wounda lifting-strap F, connected with the operating parts of the valve B.The interior of the hollow cylindrical pulley D is divided into twocompartments by partitions G and H at right angles to each other,extending from the center to the circumference and embracing one-quarterof the interior space. The partition G extends beyond the center, whenit unites with partition H, and toward the opposite circumference makinga narrow passage-way between the two portions of the larger or remaininginterior space. The partition H is provided with ahole or passagewaycommunicating with the interior of the inclosed portion, through whichthe passage of the liquid is regulated by a valve I, operated andadjusted from the outside.

A strap is attached to the pulley D at one end in the usual way, theother end projecting downward to some place from which it is convenientto operate the valve. The cylindrical pulley is also provided upon theback side with a check or stop, which defines the extent of its rotarymovement whenever the strap is pulled.

Commencing with the valve closed, as shown in Figs. 1 and 2,whenever itis desired to flush the closet a pull upon the proper strap attached tothe pulley D will cause the latter, together with the shaft 0 and pulleyE, to rotate in the direction indicated by the arrow in Fig. 1. Suchrotation of the shaft 0 and pulleyE winds up the strap F and opens thevalve B, as shown in Figs. 3 and 4, in a well-understood way. Therotation of the hollow cylindrical pulley D has the effect oftransferring the liquid contained therein from its position shown inFig. 1 to that portion of the cylinder to the left of the partition H,counterbalances the weight of the valve, and holds it in an openposition, as shown in Figs.

3 and 4. As soon as the liquid becomes deposited in its new position, asabove de scribed, it begins to pass through the partition H, andcontinues to do so until it becomes 8 5 equalized upon either side. Thevalve B will continue open until the process of equalizationsufficiently advances to change the counterbalancing power of theliquid, when it will begin to close slowly, ending with a quick andsudden movement at the last, the liquid remaining in the space inclosedby the partitions G and H passing through an aperture in the partitionG, when the whole will assume its former position, as shown in Fig. 1. 5

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination of the shaft 0, hollow cylindrical pulley D, havinginterior divisions G H, dividing the space into compart- Ico ments ofdifferent sizes and containing a movable liquid brought into aleverage-acting position by the enforced rotation of the said pulley D,with the valve B and suitable means for operating the same, the Wholeconstructed, containing a movable leverage-acting liquid, IO arranged,and operating in the manner snbwith the valve 13 and suit-able means forcpstantially as described. erating the same, the wholeco'nstructed, ar-

2. The combination of the shaft 0, the holranged, and operating in themanner substan- 5 low cylindrical pulley D, having interior ditially asdescribed, for the purpose specified.
